Usually the saying 'form follows function' works for me. Carbon fiber reel seats were fine with me because they weren't just cosmetic, they shaved weight. Another adage from the old street rod days, 'if it don't go, chrome it' also has merit. That grip though... I dunno man... does it come in cork color?
Is that grip different just to be different or does it have benefits that cork doesn't?

Considering how difficult it is to get really good cork and how freaking expensive the good stuff is - $3+ per 1/2" ring for true Flor grade - I'd guess one of advantages is cost savings.

I don't mind the looks actually. I don't really want a fire engine red grip, but I could see it looking good in black or charcoal on a custom rod.
